May be a grounding issue. There are too many things and all at once.

Re: HELP plz. CEL, P4 and ABS Codes
 

I'll start looking at how to troubleshoot and verify the ground is correct.

I agree (and hope) that it's all related to a since issue/fix.

Thanks for the reply and I'll update on how it goes this weekend.

Find it?

I couldn't find any grounding issues, everything electronic-wise had good voltage, etc.

But had a buddy who's a mechanic come over and said he thinks it's the head gasket is gone... He's bringing over a compression tester from work tomorrow, so we'll see how it goes...

Did a compression test and #4 had compression but 1-3 did not make the gauge move at all.

Buddy said it might be a blown head gasket...

Said timing might also be an issue... but all of the sudden on the timing?

Did the car overheat? did you rev it up hi? Do you have another ecu for it by chance?

The heater hose split one day and sprayed coolant everywhere so probably...

I replaced the hose and topped off the coolant and was running for a while, in limp mode with all the codes but now won't start at all.

This is my nieces car so she probably drove it for 20 miles while on fire :(

Also, after checking it looks like it has no coolant in it now... no puddle under the car nothing on the inside that I can see?

Gasket is blown hopefully no damage to head or piston rings but i highly recomend you take that head to a machine shop before you put everything back on also new water pump seal bearings timing belt and tensioner as well...gl
